Tone & Use‑Cases

• The HyDrive speaker gives a balanced, dynamic tone: you get warmth from the paper cone + punch/attack from the aluminum part.

• With only 25 W, this amp is best suited for practice, small rehearsal rooms, or bedroom playing, rather than loud gigging.

• The AUX input lets you play along with backing tracks, which is super handy for practice.

• Headphone out makes it great for quiet practice.
